1. Why is the specific gravity for infants lower than for older children?

Correct answer: D

Rationale: The correct answer is D because infants' kidneys are less developed compared to older children, making them less efficient at concentrating urine. This results in a lower specific gravity in infants. The other choices do not directly explain why the specific gravity is lower in infants.

2. A parent of an infant with congenital hypothyroidism is receiving teaching from a nurse. Which of the following statements should the nurse include in the teaching?

Correct answer: D

Rationale: The correct answer is D. Congenital hypothyroidism requires lifelong medication to manage the condition effectively. The nurse should emphasize to the parent that their child will need to take the medication for life to ensure proper thyroid hormone levels and prevent complications associated with hypothyroidism.

3. The patient with bipolar disorder is being treated with lithium and has a new prescription for captopril for hypertension. The combination of these two drugs makes which assessment particularly important?

Correct answer: B

Rationale: When captopril, an ACE inhibitor, is combined with lithium, it can lead to lithium accumulation. Therefore, monitoring lithium levels is crucial to prevent toxicity. While ACE inhibitors like captopril can cause hyperkalemia, renal insufficiency, and hypotension, the risk of these effects is not increased by the combination of lithium and captopril.

4. When a patient is taking glucocorticoids and digoxin, which electrolyte should the nurse prioritize monitoring?

Correct answer: D

Rationale: The nurse should primarily monitor potassium levels in a patient taking glucocorticoids and digoxin. Glucocorticoids can lead to potassium loss, potentially increasing the risk of digoxin toxicity. Additionally, glucocorticoids may worsen hypokalemia induced by diuretics like thiazides and loops. While calcium, magnesium, and sodium are important electrolytes to monitor in various clinical situations, they are not the priority in this specific scenario of a patient on glucocorticoids and digoxin.

5. What is an appropriate intervention for the edematous child with reduced mobility related to nephrotic syndrome?

Correct answer: B

Rationale: Changing the child's position frequently is essential for preventing respiratory tract infections and reducing pressure on delicate skin, which are common risks for edematous children with reduced mobility due to nephrotic syndrome. This intervention helps promote circulation and prevents complications associated with prolonged immobility.
